I have a 1979 450 SL recently my car only blows cold air is. The dealer told me I needed a new heater servo and quoted me 2500 to replace. Is ther a way to bypass the servo to blow only hot air until I get the funds to replace the heater servo.
I AM RESTORING A 1980 450SL AND I HAVE A QUESTION CONCERNING EXHAUST. I HAVE BEEN TOLD THAT IF YOU TAKE THE CATALYTIC CONVERTER OUT, THE FUEL MILAGE WILL SUFFER. I HAVE ALSO BEEN TOLD IT WILL RUN MUCH BETTER WITHOUT IT.
